Definitions
- the invention relates to apparatus for processing heat-softenable mineral material, such as glass, and more particularly to apparatus supporting and stabilizing a feeder for feeding a large number of streams of glass for attenuation to continuous fibers or filaments.
- Continuous fibers or filaments of glass have been made and formed into strands and yarns particularly usable in the production of fabrics and other purposes.
- the trend in the production of continuous filaments attenuated from glass streams is to increase the number of filaments attenuated from streams flowing from a stream feeder and where many hundreds of filaments are formed from streams flowing from a single feeder, the stream flow area of the feeder or bushing is of comparatively large area.
- the feeder floor which is usually fashioned of an alloy of platinum and rhodium, tends to warp or sag, a condition which adversely affects the production of continuous filaments of uniform size and characteristics.
- stream feeders or bushings having a large orifice area it becomes necessary to support the bushing in a manner to minimize sagging and warpage.
- the U.S. Pat. No. 3,334,981 to Glaser discloses support means for such a feeder or bushing.
- the support means comprises a tube having specially configurated depending end regions to avoid interference with the terminal lugs at the ends of the feeder or bushing which are connected to a source of electrical energy for heating the glass.
- the configurated end regions of the tube are mounted by a downwardly extending mounting means, a construction which is very costly.
- the present invention embraces a tubular support arrangement for a glass stream feeder or bushing floor section or stream flow area wherein the end regions of a tubular support means are connected with intermediate regions of laterally arranged tubes for conveying a cooling fluid through the tubular support means to eliminate sagging or warpage of the feeder floor.
- Another object of the invention resides in a tubular metal support member for a stream feeder floor section wherein the support member is configurated to accommodate a body of refractory disposed between the tubular member and the feeder floor section, the refractory being in the form of a rod preferably of circular cross section for electrically insulating the tubular metal member from the feeder floor.
- Another object of the invention resides in a tubular support arrangement for a glass stream feeder or bushing floor accommodating circulating cooling liquid wherein the tubular support arrangement is fashioned of metal alloy of a character tending to reduce the deposition of solid matter or scale on the interior of the tubular support arrangement resulting from precipitation of additives in the liquid.
- Another object of the invention resides in a tubular support arrangement for a glass stream feeder or bushing floor wherein the arrangement comprises tubular components which are commercially available so that the support arrangement may be fabricated without the use of special tools and at a greatly reduced cost.

- FIG. 13 is a further modification of the feeder floor support means.
- apparatus of the invention has particular utility in association with a feeder or bushing from which flow streams of heat-softened glass for attenuation into fibers or filaments, it is to be understood that the apparatus may be utilized with feeders for flowing streams of other fiber-forming mineral materials.
- a stream feeder or bushing and support means of the invention are illustrated in combination with a conventional arrangement for attenuating streams of glass delivered from the feeder or bushing into continuous filaments and collecting a strand or group of the filaments in a wound package.
- the arrangement or apparatus is inclusive of a stream feeder or bushing 10 which is arranged to be supplied with and contain heat-softened fiber-forming mineral material, such as glass, and from which flow streams of the glass for attenuation to continuous filaments or fibers particularly for textile uses.
- the feeder or bushing 10 is connected with a forehearth 12 arranged to receive refined heat-softened glass from a melting furnace (not shown).
- the feeder 10 may be associated with an arrangement wherein spheres or marbles of prerefined glass are melted in a receptacle above the feeder and the molten glass delivered into the feeder.
- the feeder 10 has a feeder floor section or bottom wall 14 provided with a substantial number of depending tips or projections 16 having orifices through which flow streams 18 of glass which are attenuated to continuous filaments or fibers 20.
- the stream feeder or bushing 10 is preferably fashioned of an alloy of platinum and rhodium or other material which will withstand the temperatures of molten glass, the end walls 22 of the feeder being provided with terminals or lugs 24 to which are secured connectors or clamps 25, one of which is shown in FIG. 3, for connection with a supply of electric current to maintain the molten glass in the stream feeder at a proper temperature.
- the glass streams are attenuated into continuous filaments 20 by winding a strand or group 27 of the filaments into a package 30 on a conventional winding machine.
- the filaments 20 are engaged with an applicator 32 of conventional construction whereby a lubricant, size or other coating material within a container or receptacle 34 is applied to the filaments by the applicator.
- the filaments are converged into a strand or group 27 by a gathering device or shoe 36 and the strand or group 27 wound upon a rotating collector, tube or sleeve 37 mounted upon a collet 38 rotated by motive means (not shown) of a conventional winding machine 40.

Disposed between the side and end walls of the feeder 10 and portions of the mounting frame 46 is refractory 50 to minimize heat loss from the glass in the stream feeder 10, the glass flow channel in the forehearth 12 being in communication with the stream feeder.
- the feeder floor section 14 is provided with several hundred orificed projections which necessitates a floor section of substantial area. Under the intense heat of the molten glass or other fiber-forming mineral material, the central region of the feeder floor or floor section 16 tends to warp or sag, a condition which promotes unstable laminar flow of the glass in the region adjacent the feeder floor.
- the invention is inclusive of a support means having a tubular means or hollow body disposed lengthwise of and beneath the floor section of the stream feeder through which cooling fluid is circulated to minimize or reduce distortion or sagging of the floor section.
- Attenuated filaments of substantially uniform size and character resides in flowing streams of glass of the same size and of uniform viscosity at all of the orifices. It is essential that a fluid or liquid be circulated through a support means in order to prevent sagging of the support means and the feeder floor.
- the support means assembly is attached to the corner regions of the rectangular mounting frame for the stream feeder in order to stabilize the elongated tubular body or support means.
- the support means and the circulating cooling liquid function as a heat sink, the circulating liquid conveying away or dissipating excess heat at a controlled rate from the region of the feeder floor section adjacent the support means so as to promote stability of the temperature and viscosity of the glass throughout the area of the feeder floor section.
- the tubular support means must be maintained out of direct contact with the metal of the feeder floor section by suitable refractory which is a nonconductor of electric energy so as not to modify the electric energy flow through the stream feeder.

- the end regions of the transversely extending tubular members 68e and 69e are provided with mounting means or plates 80e for attaching the support assembly shown in FIG. 13 to the stream feeder mounting frame 46 in the manner shown in FIGS. 3 and 4.
- tubular components of the feeder floor support assemblies illustrated in FIGS. 12 and 13 may be made of metals or alloys of the character hereinbefore mentioned in connection with the support means assembly shown in FIGS. 1 through 8.
